We’re re-organizing data to make things more efficient for future updates, which accounts for this update’s size. Please also be aware you’ll need a good chunk of free hard drive space to handle this particular update.

The good news is that this patch also contains the highly anticipated Pet Battles system!

We really appreciate your continued testing efforts – you’ve been a great help to ensuring we release a great expansion.

You can head over there now to read all about the new system, learn how your pets will fight for glory and victory, and look at several screenshots of pets in action.

For all those testing the new system, please join the Pet Battles discussion in our beta feedback forum.

I thought when they announced Ascendance's ele effect, great, Lava burst will be nerfed now -- and look. Thankyou Blizzard, for giving us a skill that potentially will do more damage to the feel of our spec than good.

Ascendance isn't even much more burst than what we had. The old EM was a pretty huge burst cooldown but they removed the damage increase effect and put it as a talent for pure haste. The damage increase over old EM is not as good as some may think, I believe this change pushes us to the bottom of the barrel in terms of DPS now while offering nothing unique to a raid. Go resto or go home. Between the 25% nerf to lavaburst through L90 talents, and now the scaling nerf you're probably better off going enhance at this point.

Nono, I'm certain it's without the nerf-debuff that you those feats, since they'll be adding a nerf like DS/ICC I think, so you get something for doing it without, I pray they give you a title or something though, just FoS aren't gonna motivate too much..

Yeah not to happy with the Lava Burst nerf either but knew it had to happen sooner or later, but yeah such a big hit for sure..

Cutting Edge: Grand Empress Shek'zeer (New) Defeat Grand Empress Shek'zeer in Heart of Fear on Heroic difficulty, with Klaxxi Resonance inactive or disabled.
Cutting Edge: Sha of Fear (New) Defeat the Sha of Fear in Terrace of Endless Spring on Heroic difficulty, with the Ritual of Purification inactive or disabled.
Cutting Edge: Will of the Emperor (New) Defeat the Will of the Emperor in Mogu'shan Vaults on Heroic difficulty, with the Dampening Field either inactive or disabled.

Hardmodes? Aww yeaaah

Sounds like Feats of Strength for doing Heroic without the % buffs/debuffs (as in the gradually increasing optional nerfs they introduce to help guilds clear current content ala Dragon Soul (power of the aspects) and Icecrown (Hellscreams warsong/whatever alliance got)).

Predatory Swiftness Your finishing moves have a 20% chance per combo point to make your next Cyclone, Entangling Roots, Healing Touch, Hibernate, or Rebirth become instant, free, and castable in all forms. srsly blizz, wtf?

I agree that a title and/or mount (or some other vanity item) would be appropriate for players achieving these feats. Hopefully, the FoS isn't the only change.

Mistweavers got a swift kick between the knees right there. I can accept the amount of healing some of the spells being toned down a bit, but the increased mana cost feels unwarranted. The increased CD on Renewing Mist didn't feel needed as well.
